Blasting cartridge, percussion cap, detonator, detonating fuse, and the like



Patented Jan. 14, 1930 PATENT OFFICE OLDRICH TUREK, 9F PLZEN,GZECHOSLOVAKIA BLASTING CARTRIDGE, PERCUSSION GAP, DETONATOB,DETONATING'FUSE, AND THE LIKE No Drawing. Application filed February 25,1929, Serial No. 342,672,

2, 4, G-trinitro 1, 3, -triazidobenzene can be suitably employed aspriming in detonating caps, if the compression pressure does not exceeds300 kg. cm otherwise there is a rapid 5 decrease in shattering power andpriming force.

The same powerful action which is obtained with the type of detonatingcaps in which highly compressed 2. 4, fi-trinitro 1, 3, 5-tri- 10azidobenzene is combined with highly compressed lead azide, is alsoobtained with detonating caps, in which use is'made, as secondaryfilling, of highly compressed 2, 4, 6-trinitro 1, 3, 5-triazidobenzene(compression pressure of 300 kg. cm u to 2000 kg. cm and more) and aspriming lling a small length of slightly compressed 2, 4, fi-trinitro 1,3., 5-

triazidobenzene. 0.05 grms. to 0.1 grms. of

this substance, which has been compressed under a pressure of 300 kg. cmis suitable for the purpose.

As secondary filling in place of highly compressed 2, 4, S-trinitro 1,3, 5-triazidobenzene, use can also be made of trinitrotoluene, tetril orother shattering substance; the shattering power of the detonating capsis naturally correspondingly less. 0.5 grms. 2, 4, 6-trinitro 1, 3,5-triazidobenzene is sufiicient for complete priming.

What I claim is 1. A method of producing blasting cartridges and thelike, consisting in filling the detonating cap with compressed 2, 4,6-trinitro 1, 3, 5-tri'azidobenzene, serving as secondary filling, andramming thereupon with a pressure not exceeding 300 kg. cm a primingconsisting of 0.05 to 0.2 guns of 2, 4, fi-trinitro 1, 3,5-triazidobenzene, as set forth.

2. A method of producing blasting cartridges and the like, consisting infilling the detonating cap with compressed 2, 4, 6-trinitro 1, 3,5-triazidobenzene, serving as secondary filling, ramming thereupon witha pressure not exceeding 300 kg. cm a priming consisting of 0.05 to 0.02grms. of 2, 4, 6-trinitro 1, 3, 5-triazidobenzene, and pressing thereona protective cap with aperture, as set forth.

3. A method of producing blasting cartridges, detonators and the like,consisting in and in Czechoslovakia March 28, 1928.

filling a detonatin capwith compressed trinitrotoluene, tetry or othershattering substance (high explosive) serving as secondary filling,ramming thereupon w1th a pressure not exceeding 300 kg. cm a primingconsistmg of 0.05 to 0.2 grms. of 2, 4, G-trinitro 1, 3,5-triazidobenzene and pressing thereon a protective cap with anaperture, as set forth.

In testimony whereof I have signed my name to this specification.

OLDRIOH TUREK.
